There's nothing to worry about, it won't be EOS for a while and by then you'll want to upgrade hardware anyway. I still have an XTM 525 in use as well as an M400, and hundreds of clients range from 515 to T10, and still some 25 and 26's. We typically upgrade the hardware if and when they run a special that brings it close in price to the UTM renewal.

The M370 offers a number of improvements in speed and
capability over the M300. As new technology becomes available, WatchGuard, like many any other hardware and software vendors, will always release new products that
take advantage of that tech. However, have no fear, your M300 is still a powerful device and will still serve you well. And as Jim mentioned above, when the time comes, an upgrade is always recommended.
